OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

In the present paper, the contribution of the largest principal component and the number of principal component needed for accumulative contribution 95% are selected as indices of electroencephalogram (EEG) in mental fatigue state in order to investigate the relationship between these parameters and mental fatigue. The experimental results showed that the contribution of the largest principal component of EEG signals increased in the prefrontal, frontal and central areas, while the number of principal component needed for accumulative contribution decreased by 95% with the increasing mental fatigue level. The parameters of singular system of EEG signals can be regarded as useful features for the estimation of mental fatigue and have larger application value in the study of mental fatigue.

Objective To investigate the effect and mechanism of ischemic postconditioning (IPC) on myocardial perfusion levels of acute ST-segment elevation myocardial infarction (STEMI) patients having underwent primary percutaneous coronary intervention (PCI), and the safety of IPC. Methods One hundred and sixty patients with STEMI were enrolled, and they accepted the primary PCI therapy within the onset of 12 h. The patients were divided into 2 groups according the treatment method:control group (routine PCI group, 82 cases) and IPC group (78 cases). The ST-segment resolution, TIMI myocardial perfusion grade (TMPG), before and after PCI levels of nitrogen monoxidum (NO), endothelin (ET)-1, tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor (PAI)-1, rate of intraoperative complication were observed. The patients were followed up for 6 months, the rate of major adverse cardiac event (MACE) was recorded. Results The rates of ST-segment resolution and TMPG well in IPC group were significantly higher than those in control group:84.62%(66/78) vs. 67.07%(55/82) and 80.77%(63/78) vs. 64.63%(53/82), and the rate of ischemia-reperfusion injury in IPC group was significantly lower than that in control group: 7.69%(6/78) vs. 24.39%(20/82), and there were statistical differences ( P<0.05 or<0.01). The endothelial function and fibrinolysis activity indexes (NO, ET-1, t-PA and PAI-1 levels ) 7 d after PCI in IPC group were significantly better than those in control group: (52.37 ± 3.84) μmol/L vs. (50.95 ±3.85) μmol/L, (75.47 ±3.47) ng/L vs. (76.61 ±3.72) ng/L, (12.96 ±1.25) μg/L vs. (12.52 ±1.23) μg/L, (21.78 ±4.01)μg/L vs. (24.95±7.56)μg/L, and there were statistical differences (P<0.05 or<0.01). There was no statistical difference in the rate of intraoperative complication between 2 groups ( P>0.05). The rate of MACE in IPC group was significantly lower than that in control group:3.85% (3/78) vs. 14.63% (12/82), and there was statistical difference (P<0.05). Conclusions Applying IPC in patients with STEMI having underwent primary PCI is safe and can improve myocardial perfusion levels. The improvement of vessel endothelial function and fibrinolysis activity attained from IPC may be the major mechanism.

BACKGROUND:Single fracture or colapse of the posterolateral tibial plateau fractures is relatively rare in the clinical work. Rational choice of surgical approach and internal fixation for posterolateral plateau fracture is significant to restore the lower limb force line, maintain the joint stability and obtain good biocompatibility.
OBJECTIVE:To compare the stability and biocompatibility of Carlson posterolateral and posterior midline approaches for the treatment of posterolateral tibial plateau fractures with “T” shaped locking plate.
METHODS:From July 2011 to July 2014, 43 patients with posterolateral tibial plateau fractures, who were treated in the Affiliated Hospital of Jining Medical University, were retrospectively analyzed. Al patients were assigned to two groups according to approaches. In the Carlson posterolateral approach group, 22 cases received “T”-shaped plate insertion by Carlson posterolateral approach. In the posterior midline approach group, 21 cases received “T”-shaped plate insertion by posterior midline approach. After repair, perioperative data, fixation effects and knee function score were compared and analyzed between both groups.
RESULTS AND CONCLUSION:(1) 43 cases (43 knees) of posterolateral tibial plateau fractures were folowed up strictly. (2) No significant difference in operation time, fracture healing time, total load time, Hospital for Special Surgery score at 12 months postoperatively, tibial plateau angle and posterior slope angle immediately and 12 months postoperatively was detected between both groups (P > 0.05). (3) Significant differences in fracture exposure, blood loss, and excelent and good rate of Rasmussen at 12 months postoperatively were identified in both groups. Moreover, above indexes were better in the Carlson posterolateral approach group than in the posterior midline approach group (P< 0.05). (4) These findings confirmed that for a single fracture or colapse of the posterolateral tibial plateau fractures, two kinds of surgical approaches can achieve ful and direct exposure. Carlson posterolateral approach has good repair effect, fixation effect and biocompatibility.

Objective To investigate the level and proportional relationship of free fluorine and soluble fluoride in different brands of toothpaste,and analyze possible risk factors.Methods A total of 54 samples of commercially available toothpastes of domestic,joint venture and imported in Guiyang City were collected,and the levels of free fluoride and soluble fluorine were determined,respectively,using fluorideion selective electrode.method (GB 8372-2008).Results The number of the toothpaste was 32,12,10,respectively,in domestic,joint venture and imported.The levels of free fluorine ranged from 0.98 to 1 603.50 mg/kg,3.22 to 617.50 mg/kg and 306.80 to 1 590.80 mg/kg,respectively,in toothpastes of domestic,joint venture and imported; the number of exceeding the standard free fluorine was 3,0 and 1,respectively,in toothpastes of domestic,joint venture and imported; the rate of exceeding the standard free fluorine was 9.4％,0.0％ and 10.0％,respectively,in toothpastes of domestic,joint venture and imported.The levels of soluble fluorine ranged from 3.06 to 4 302.50 mg/kg,9.02 to 1 667.30 mg/kg and 9.18 to 4 013.20 mg/kg,respectively,in toothpastes of domestic,joint venture and imported; the number of exceeding the standard soluble fluorine was 9,2 and 3,respectively,in toothpastes of domestic,joint venture and imported; the rate of exceeding the standard soluble fluorine was 34.4％,16.7％ and 30.0％,respectively,in toothpastes of domestic,joint venture and imported.The proportion of free fluorine and soluble fluoride was:domestic 1.0 ∶ 2.7,joint venture 1.0 ∶ 2.7,imported 1.0 ∶ 2.5,respectively.The confidence limit (R/d) was 0.98.Conclusion The fluoride level in different brands of toothpaste has exceeded the standard,the content and proportion of soluble fluoride are obviously higher than those of free fluoride,and there is a risk on tooth damage from fluoride,and factories should strengthen quality control in adding fluoride.

ObjectiveTo investigate the distribution and expression of y-secretase subunit (APH-1)in the central nervous system (CNS) of APP/PS1 double transgenic Alzheimer's disease (AD) adult mouse model,and to detect the expression difference of APH-1 in developmental brain between AD model mouse and wild-type littermates in order to further clarify the relationship between APH-1 and AD. MethodsOffspring bred by APP/PS1 double transgenic AD mice were genotyped.Immunohistochemical staining was used to detect APH-1 distribution and expression in the CNS of adult APP/PS1 double transgenic AD mouse model,in the brain of AD model mouse and its wild-type littermates on postnatal day 1,7,21 and 120.Results APH-1 was widely expressed in almost all regions of the CNS,especially in the cerebral cortex,hippocampus,olfactory bulb,hypothalamus,ventral striatum,caudate putamen,raphe magnus nucleus,cerebellum,brainstem and spinal cord of the adult APP/PS1 double transgenic mice.APH-1 expression was higher in the cortex of both AD and wild type mouse on postnatal day 1 than on postnatal day 7 and 21 with increased level of APH-1 protein in adult mouse brain.APH-1 expression in the brain of AD mice was higher than in its wild type littermates at any stage(P＜0.05).Conclusions Distribution of APH-1 is ubiquitous and region-dependent in the CNS.The different distribution and expression between APP/PS1 double transgenic mouse model and its wild type littermate indicate that APH-1 may be related to AD.

Thirty patients with objective benign paroxysmal positional vertigo (BPPV) (objective group) and 30 patients with subjective BPPV (subjective group) visiting Department of Neurology from January 2014 to June 2015 were enrolled in the study.There were no significant differences in semicircular canal,gender,age,related factors of secondary onset (P ＞ 0.05).Patients were evaluated with dizziness handicap inventory (DHI) before and after the maneuver therapy.The average DHI subscale scores before treatment of all patients were higher than those after treatment (11.8 ± 2.8 vs.2.5 ± 1.8,P ＜ 0.05);there was 11.9 ± 3.0 vs.2.5 ± 2.1 (P ＜ 0.05) for objective group and 11.6 ± 2.6 vs.2.5 ± 1.6 (P ＜ 0.05) for subjective group.The scores of PI,F5,P11,P13,P25 (mean rank order value) after treatment were decreased compared to corresponding initial scores in two groups(objective group:21.30 vs.39.70,19.55 vs.41.45,19.00 vs.42.00,18.65 vs.42.35,15.90 vs.45.10,respectively,subjective group:20.93 vs.40.07,18.07 vs.42.93,19.77 vs.41.23,18.57 vs.42.43,16.47 vs.44.53,respectively;all P ＜ 0.05).The results indicate that maneuver therapy is effective both for objective and subjective BPPV patients;and subscale of DHI can be used to evaluate the degree of illness in patients with BPPV.
